What causes women's skin to darken?

Many female friends have found that their skin was relatively white at the beginning, but for some unknown reason, the melanin on their face becomes more and more, and gradually becomes darker, seriously affecting their own image. They themselves do not know what causes this phenomenon. So, what is the reason why women’s skin becomes darker? Let us give you some basic knowledge!

1. The foods you like are rich in zinc, copper and iron. Certain foods are also the cause of darkening of the skin. Foods rich in metal elements such as copper, iron, and zinc have this disadvantage. These metal elements can directly or indirectly increase the amount and activity of substances such as tyrosine and tyrosinase that are related to melanin production. These foods mainly include animal liver, kidney, oysters, shrimp, crab, beans, walnuts, black sesame, raisins, etc.

2. The drug has affinity to melanin. Many drugs also change the normal skin color. For example, chloroquine has a strong affinity for melanin, which aggravates skin discoloration; about 10% of patients taking quinine develop blue pigment spots on their faces. Sedatives pose the greatest threat to skin color. Those who take them for a long time will develop butterfly spots on their face and neck, and their arms and other parts will turn brown-gray, light blue or light purple. In addition, repeated use of mercury-containing ointments can also leave brown pigmentation on the affected area. There are more anti-cancer drugs that cause skin color changes.

3. The natural environment damages the skin. The culprit is ultraviolet rays, which stimulate the melanin in the skin and induce skin lesions such as freckles. Even on cloudy days, the "ultraviolet rays" are still strong. Ultraviolet rays can cause skin darkening, aging, and wrinkles. Human skin's response to ultraviolet rays causes redness, tanning and increased thickness of the skin's epidermis in acute reactions, and leads to skin aging in chronic reactions. In the summer, if you still want to have fair and flawless skin, you should do a good job of sun protection, especially when the UV index reaches 7 or above, it is more likely to damage the skin. You should strengthen sun protection and don't be afraid of trouble and cause regret in the future. In fact, humid air, sunlight coming through car windows, and even indoor light bulbs and computers are all the culprits that cause your skin to become darker.

4. Certain diseases are triggering factors. Many diseases can change the normal skin color and make it darker. The most common ones include endocrine system diseases, chronic wasting diseases, malnutrition diseases, etc. These diseases can cause the skin to turn brown or dark brown, which is particularly obvious in exposed areas such as the face, back of the hands, joints, or areas that are under pressure and friction. For example, chronic liver disease can cause chloasma on the face or darkening of the area around the eye sockets. In addition, the melanin of melanosis patients is mostly accumulated on the face, especially on the forehead, cheeks, behind the ears and neck, which is very obvious. Another type of disease is skin diseases, especially skin diseases caused by allergies to certain foods, such as raw onions, raw garlic, peppers, peppers, leeks, wine, fish, shrimp, kelp, chicken, duck, pig's trotters, pig's head and other foods, which can also induce skin allergies, resulting in rashes and finally leaving pigments to make the skin darker.

The above reasons are all causes of darkening of the skin. You should pay more attention to it in your daily life. The indoor room should not be too dark. Long-term exposure to light tubes and computers will seriously harm your skin. Therefore, friends who work next to computers for a long time should pay more attention to it and try to take some measures to prevent radiation.
